Document Summary
Genetics and personality: genetics play a huge role in personality (other factors also do) Identical twins have 100% genetic match vs. fraternal twins that have 50% genetic match. Concordance rates between the identical and fraternal twins significantly higher concordance rate for the identical twins, this suggests that genetics plays a role in personality. Also instances when biological twins are separated and raised in different environments stronger correlation concordance rate with biological parents and biological children than with foster parents/adopted children.
